Referring-to the drawings, the numeral 28 desigates generally a mobile frame formed of lower 3' Claims. (Cl. Mei-246) frame bars 2!, having pairs of wheels 22 and 23 secured to the opposite ends thereof, the wheels 23 being steerable wheels having a drawbar 2 associated therewith. The frame 20 includes upright end members 25 and 28 at the front and rear ends respectively of the frame, and front and rear crossbars 2 l and 28 which are secured between the uprights 25 and 28 respectively.

A pair of longitudinal frame members 30 and 31 are connected, between the uprights 25 and 25 and between the horizontal end members '2'! and 23. Intermediate connecting bars 32 and 33 are secured between the side bars 39 and Si and a pair of intermediate longitudinal supporting bars 34 and 35 are secured between the intermediate bar 32 and the forward bar 27'.

A lower pair of upwardly divergent roller supporting bars 36 and 31 are secured to upwardly divergent supporting bars 38 and 39 respectively, which are secured to the upper frame members 21, 23, 22 and 33. An upper pair of elongated roller supporting bars lu and 4| are disposed in upwardly divergent relation and are slidable on the inner faces ofthebars 38 and 39 which constitute guides for the slide bars 40 and 4|.

The stationary and movable bars 36, 31, 40 and il have mounted adjacent each end thereof idler rollers :52, and the idler rollers 42, as shown in Figure 10, are rotatably carried by a U-shaped bearing 3 which is pivotally secured by means of a pivot bolt 5 to the stationary lower bar 36, and is pivotally secured by means of a pivot bolt 45 to the movable bar There are two of the rollers 32 adjacent each end of the frame structure for supporting the log as it is moved endwise through the machine.

Opposed pairs of log rolling and moving rollers 46 are secured to the bars fifiand ii], and ii and 4H, after the manner of the idler rollers is. The rollers 56 are toothed rollers, being mounted on a U-shaped bearing or saddle 41, as shown in Figure 12. The saddle if is pivotally secured by means of a pivot bolt 28 to the lower stationary bar 353 and is pivotally secured by means of a pivot bolt 59 to the upper movable bar 30. It will be understood that the bars 31 and 4! have rollers '32 and rollers it secured thereto in the same manner as the rollers secured to bars 36 and Ml. The rollers connected to each pair of elongated bars are disposed in parallel relation and are positioned on an oblique angle with respect to the length of the bars 36, 31, 40 and ll, as shown in Figure 2. V V

In order to provide a means whereby the angular relation of the rollers 42 and lliv may be adjusted to provide for accommodating logs of different sizes so that these logs will move lengthwise through the machine at the desired rate, and will also be rotated at a uniform rate within the trough formed by the rollers, I have provided a roller adjusting means as shown in Figure 15. This adjusting means comprises a pair of upwardly divergent rod 50 and 5| which are pivotally secured to the longitudinal roller supporting bars 40 and 4| respectively, and the lower convergent ends of the rods 50 and 5| are pivotally secured, as shown in Figure 16, to a pair of plates 52 and 53 carried by a slide block 54, suitable spacers 58a and am being provided. The slide block 54 is slidable on a vertically disposed guide rod 55 which is fixed by means of a supporting bar 59 to the stationary bars 36 and 3! and is braced at its lower end by means of a bracing bar 51.

A pusher block 58 is slidable on the supporting bar 55 below the slide 54 and has pivotally connected therewith one end of a slide adjusting link 59. The other end of the slide adjusting link 59 is pivotally connected with a crank arm 60 (see Fig. 3) secured to a shaft 6| rotatably carried by supporting members 62. The shaft 6| extends toward the rear or intake end of the machine and has fixed thereon an upwardly extending crank arm 63 which has connected therewith an elongated link 64. The link 64 is pivotally connected to a hand lever 65 which has associated therewith a toothed quadrant 66 so that the adjustable roller carrying bars 4| and 42 may be manually adjusted upwardly or downwardly to accommodate logs of various sizes.

The toothed rollers 46 are rotated by means of a drive shaft 69 journalled lengthwise of the frame 20 and rotated by means of a chain which engages a, sprocket wheel 1| fixed to the shaft 69. The chain 10 also includes a sprocket wheel 12 secured to a countershaft I3, and a reduction gearing I4 of conventional construction is connected with shaft 13.

A driving pulley or wheel is fixed to a shaft 59 which is connected with the reduction gearing, and a, belt 11 engages about the wheel 15 and also engages about a driving wheel 18 secured to a motor or power shaft 19. The power shaft 19 is operated by means of a power member 80 of conventional construction.

Each roller 46 is rotated by means of a chain 8| which engages about a sprocket 82 secured to the drive shaft 69, and chain 8| also engages about a sprocket 83 secured to a stub shaft 84. The stub shaft 84 is supported from bearings 85 fixed relative to the frame 20, and stub shaft 84 is connected with a roller 46 by means of a connecting shaft 86, and a pair of universal joints 81.

A flail member generally designated as 88 is rotatably carried by a pair of inwardly projecting arms or bars 89. The arms 89 are rockably mounted at their rear ends on a shaft 90 journalled in bearings 9| fixed to upright supporting bars 92. The upright bars 92 extend upwardly from the side bar 30 at a, point substantially midway between the length of the side bar 30.

The flail member 88 comprises a drum 93 having a plurality of staggered chain lengths 94 secured thereto which are so staggered as to contact substantially the entire area of the log as the chains are swung about by rotation of the flail member 88. The flail member 88 is secured to a shaft 95 journalled in bearings 96 secured to the forward ends of the arms 89, and a pair of pulleys 91 are secured to the opposite ends of the shaft 95 and have belts 98 trained thereabout.

4 The belts 98 are also trained about rear pulleys 99 fixed to the shaft 90, and a driving pulley I00 is also fixed to shaft and has a belt |0| engaging thereabout which also engages about a pulley I02 secured to motor shaft 19.

The uprights 92 are braced by means of upwardly and rearwardly inclined bracing bars I03 (see Fig. 5) secured between the transverse frame members 32 and 33, and the upper ends of the uprights 92. Preferably a horizontally disposed connecting bar I04 is secured between the upper ends of the uprights 92. The flail supporting arms 89 are vertically adjusted at their forward or free ends as follows:

A downwardly extending L-shaped lever I05 is fixed to each arm 89 adjacent the rear thereof, being braced by means of a bracing bar I06. The lower short arm I01 of each lever I05 has connected therewith the upper end of a lever arm I09 secured to a shaft I09, which is journalled in bearings H0. The arms I08 are provided with elongated slots III through which a pivot pin I I2 carried by the arms |0'| loosely engages. The shaft I09 has secured to one end thereof a depending lever arm 3 which is connected to an adjusting lever M4 by means of a link II5. Forward or rearward rocking of hand lever 4 will rotate shaft I09 so that L-shaped lever I05 will be rocked forwardly or rearwardly to thereby vertically adjust flail supporting arms or bars 89. The flail supporting arms 89 are adapted to be substantially balanced by means of balancing weights I I6 which are adjustably secured to rearwardly projecting supporting bars II'I fixed one to each of the supporting bars 89.

In the use and operation of this machine, the log which is to be debarked or rossed is disposed in a trough formed by the opposed pairs of idler rollers 42 and toothed rollers 46. The rollers are adjusted angularly with respect to the length of the frame, to provide for the desired endwise movement of the log by adjustment of hand lever which will raise or lower the slide bars 40 and 4| and thereby vary the angular relation of the toothed and idler rollers with respect to the length of the frame. Rotation of the toothed rollers 46 will provide not only for rotating the log about the axis thereof, but the angular positions of the rollers 46 will also provide for endwise movement of the log simultaneously with the rotation thereof.

Flail member 88 upon rotation thereof will cause the chains 94 to strike the bark of the log so as to knock the bark off. The flail member 88 is adapted to be vertically adjusted by lever 4 so that the chains 94 will strike the outside of the log in a manner to properly debark the log.

A pair of swivably mounted rollers II8 are secured to the lower sides of the flail supporting bars 89 for engagement with the upper side of the log so that the supporting bars 89 may be swung downwardly if desired to a point where the free ends of the bars 89 will be supported by the swivel or caster rollers ||8 engaging the log.

I do not mean to confine myself to the exact details of construction herein disclosed, but claim all variations falling within the purview of the appended claims.

What I claim is:

l. A log debarking machine comprising a frame, a, plurality of upwardly divergent bars fixed to said frame, a lower pair of elongated bars fixed to said divergent bars, an upper pair of elongated bars slidable on said divergent bars, a, plurality of U-shaped bearing members, rollers carried by said bearing members, means pivotally securing said bearing members between said upper and lower bars, and means connecting said upper bars to said frame, said means being operable to shift said upper bars relative to said lower bars to thereby vary the angular relation of said rollers with respect to the length of a log.

2. The construction of claim 1 wherein the means operable to shift the upper bars includes a guide post, a block slidable on said guide post,

and means pivotally connecting the upper bars 10 to said slide block.

3. The construction of claim 1, wherein the means operable to shift the upper bars includes a guide post, a block slidable on said guide post, means pivotally connecting the upper bars to said slide block, a pusher block slidable on said guide post beneath said slide block, and a multiple linkage connecting said pusher block to a framemounted operating lever.
